Realization of field estimation with sensors designed using low power and low cost components

In this paper, we first form a sensor using low power and low cost components, that is, MSP430G2553 microcontroller, nRF24L01+ communication unit, and a Light Dependent Resistor (LDR). Then, by communicating such sensors with a Fusion Center (FC), we form a Wireless Sensor Network (WSN). Sensors measure the light intensities at their locations and send their measurements to the FC. Then, FC forwards the sensor measurements to the computer which performs field estimation using ordinary kriging. Our test results show that the predicted field measurement using ordinary kriging at a specific location is quite close to the actual sensor measurement at that location.
